This guide will show you how to replace a Pentair Globrite pool light step by step. You’ll learn which tools you need, how to prepare, important safety tips, and how to avoid common mistakes. Whether you want to save money on repairs, or simply like doing things yourself, you’ll find everything you need to know here.

Let’s get started and bring your pool back to life with new, vibrant lighting.

Understanding Pentair Globrite Pool Lights

Before you start replacing your pool light, it helps to know what makes the Pentair Globrite special. These lights use LED technology, which means they use less energy and last longer than old-fashioned incandescent bulbs. Globrite lights are designed for small spaces and shallow areas, making them popular for steps, tanning shelves, and tight corners.

One unique feature of the Globrite is its sealed, water-tight housing. This protects the electrical parts from water, but also means you can’t just change a bulb – you must replace the whole light fixture. The light connects to a power cable that runs through a special conduit, keeping everything safe and tidy.

Most Globrite lights can last up to 50,000 hours, but sometimes water can get inside, or the LEDs stop working. When this happens, you’ll notice the light is dim, flickers, changes color unexpectedly, or fails to turn on at all.

When To Replace Your Pentair Globrite Light

How do you know it’s time to replace your Globrite pool light? Here are some clear signs:

• No light at all: The light does not turn on, even when you check the breaker or pool light switch.
• Flickering or dimming: The light sometimes works but is much weaker or blinks.
• Color problems: The light is stuck on one color or changes colors randomly.
• Water inside the lens: You see fog, condensation, or actual water inside the light cover.

Sometimes, the problem can be with the transformer, wiring, or a remote control. Always check these first before replacing the whole light. If you see water inside the lens, it is important to replace the light immediately, as water and electricity are dangerous together.

Tools And Supplies You Will Need

To replace your Pentair Globrite pool light, gather these tools and supplies before you start:

• New Pentair Globrite light fixture (make sure it matches your pool’s voltage and color options)
• Screwdrivers (usually a Phillips or flat-head)
• Needle-nose pliers
• Pool light cord stopper (often rubber or plastic, may come with the new light)
• Pool light niche gaskets (these prevent leaks and should be replaced if old)
• Silicone lubricant (for waterproofing connections)
• Electrical tape
• Circuit tester (to confirm power is off)
• Bucket or small container
• Clean towel or rag

Optional but helpful:

• Garden hose (to flush the conduit if needed)
• Cord pulling lubricant (makes it easier to pull the new cord)
• Plastic fish tape (for guiding the new cable through the conduit)

Having everything ready will save you time and prevent frustration during the project.

Safety First: Important Precautions

Working with electricity and water is dangerous if you are not careful. Always follow these safety steps:

• Turn off power at the breaker: Never trust just the pool switch. Go to your circuit breaker panel and turn off the power for the pool light circuit.
• Double-check with a tester: Use a circuit tester to make sure no power is flowing to the light.
• Never work on a wet deck: Make sure the pool deck is dry to avoid slipping or accidental shocks.
• Work during daylight: Good light helps you see what you’re doing and reduces mistakes.
• Do not touch water and wires together: Keep all wires dry until everything is sealed.

If you feel unsure at any step, do not take risks. Call a licensed pool electrician for help.

Removing The Old Globrite Light

Now that you are prepared, let’s start removing the old Pentair Globrite light from your pool.

1. Turn Off All Power

Go to your home’s breaker panel and shut off the circuit that powers the pool lights. Flip the breaker switch to OFF. Double-check with a non-contact voltage tester at the pool light switch and at the junction box (if accessible).

2. Locate The Light And Remove The Faceplate

Find the Globrite light in your pool. Most Globrite lights are installed in a special niche (a small opening in the pool wall) and covered by a faceplate.

Use your screwdriver to remove the screw(s) holding the faceplate. Place screws in a safe spot (like a small bucket) so they don’t fall in the pool.

Gently remove the faceplate. You may need to wiggle it if it’s stuck. If there is a gasket, set it aside for inspection.

3. Free The Light Fixture

Carefully pull the Globrite light out of the niche. The power cable will let you pull the light a short distance (usually 1-3 feet) out of the pool wall.

Lay the old fixture on a towel on the pool deck to keep it clean and dry.

4. Trace The Power Cable

The cable runs from the back of the light, through a conduit, to a junction box (usually outside the pool, sometimes in a nearby yard box). You may need to lift a plastic cover or unscrew a box lid to find where the cable ends.

Take a photo or make a note of how the cable is connected inside the box. This will help you connect the new light correctly.

5. Disconnect The Old Cable

Use your screwdriver and pliers to disconnect the old wires. Usually, you’ll see three wires: black (hot), white (neutral), and green (ground). Some systems may use different colors, so double-check.

Loosen the wire nuts or connectors and remove the old cable. If there is electrical tape or putty, remove this as well.

6. Remove The Old Light Fixture And Cable

You now need to pull the old cable out through the pool wall. Usually, you can pull gently from the pool side, feeding the cable into the water and out through the niche.

If the cable is stuck, do not force it. Try moving gently back and forth. Sometimes, debris inside the conduit can block the cable. You can flush the conduit with water from a hose or use a plastic fish tape.

Once the old cable is free, set the old light fixture aside for proper disposal.

Preparing The New Globrite Light

Now it’s time to get your new Pentair Globrite light ready for installation.

1. Inspect The New Light

Check the new fixture for damage, missing parts, or problems. Make sure you have the right voltage (12V or 120V), the right cord length (it must be long enough to reach from the pool wall to the junction box with extra slack), and the right color features.

2. Prepare The Niche And Gasket

Clean the light niche in your pool wall. Remove old gasket material, dirt, or algae. A clean surface helps prevent leaks.

Place the new gasket (or reuse a good condition one) in the groove around the faceplate.

3. Lubricate The Cable

Lightly coat the new cable with silicone lubricant or cord pulling lubricant. This will help the cable slide through the conduit smoothly and prevent damage.

Pro tip: Beginners often skip this step, but a sticky cable can get stuck and make installation much harder.

Pulling The New Cable Through The Conduit

This part can be tricky, especially if your conduit bends or is old.

• Attach the new cable to the old cable: If you haven’t already removed the old cable, you can tie the new cable to the old one using electrical tape. As you pull out the old cable from the junction box side, it will pull the new cable in. If the old cable is already out, you may need to use fish tape to guide the new cable through.
• Pull gently and steadily: Never yank or force the cable. If you feel resistance, pull back a little, twist, and try again.
• Leave extra slack: Leave about 3 feet of extra cable at the pool light end. This allows you to remove the light for future repairs without having to pull the whole cable again.
• Check for smooth movement: Make sure the cable moves freely and does not pinch or scrape.

Wiring The New Light

Now, let’s connect your new Globrite light to the pool’s electrical system.

1. Connect Wires At The Junction Box

At the junction box, strip about half an inch of insulation from the ends of each wire. Match the colors carefully:

• Black to black (hot)
• White to white (neutral)
• Green to green or bare copper (ground)

Use new wire nuts and wrap each connection with electrical tape for extra safety.

2. Seal The Box

Make sure all wires are tucked neatly into the box. Close the cover tightly to keep out water and insects.

Non-obvious insight: Some pool junction boxes have a small drain hole. Make sure this is clear, so if water does get in, it can drain out.

Installing The New Globrite Light In The Pool

The final steps will place your new Globrite light safely in the pool wall.

1. Feed The Cable Into The Niche

Pull the cable gently into the niche, coiling extra slack behind the light. This is important for future maintenance.

2. Install The Cord Stopper

Place the rubber or plastic cord stopper around the cable where it enters the conduit. Press the stopper into the conduit opening to seal out water. Some stoppers need a bit of silicone lubricant to slide in smoothly.

3. Position The Light

Carefully fit the new light into the niche. Align the holes for the screws.

4. Attach The Faceplate

Place the faceplate over the light, with the gasket in place. Secure it with screws. Do not overtighten, as this can crack the faceplate or strip the holes.

5. Final Checks

Wipe away any water or debris from the area. Double-check that the light is snug and the faceplate is sealed all around.

Testing And Final Steps

You’re almost done! Here’s how to finish the job safely.

1. Restore Power

Go back to the breaker panel and turn the power back ON.

2. Test The Light

Use the pool light switch or remote control to turn on the light. Cycle through color modes (if your model supports this) to check for correct operation.

If the light does not work, turn off the power and check all connections again.

3. Inspect For Leaks

Look at the faceplate and cable entry for bubbles or leaks. If you see water entering, turn off power and reseal the gasket or cord stopper.

4. Clean Up

Put away tools, throw out old parts, and wipe down the pool deck.

Common Mistakes To Avoid

Replacing a Pentair Globrite pool light can go wrong if you’re not careful. Watch out for these common errors:

• Forgetting to turn off the power: This is dangerous. Always double-check.
• Using the wrong voltage light: A 120V light on a 12V system won’t work and can be unsafe.
• Pulling too hard on the cable: This can damage the cable or conduit.
• Skipping the gasket or cord stopper: Water leaks can ruin your new light.
• Not leaving enough slack: Makes future repairs much harder.
• Mixing up wire colors: Can cause short circuits or damage.

Non-obvious insight: If your conduit is blocked or damaged, a pro may need to use special tools, which raises the cost.

How To Extend The Life Of Your New Globrite Light

A little care goes a long way. Here’s how to keep your Pentair Globrite light working longer:

• Check for leaks each season: Look for condensation in the lens or around the cable.
• Keep chemicals balanced: Too much chlorine or low pH can damage seals and LEDs.
• Clean the faceplate: Wipe off algae or scale with a soft cloth – do not use abrasive cleaners.
• Inspect wiring during pool maintenance: Look for loose wires in the junction box.
• Turn off lights during storms: Lightning can damage LED drivers.

Upgrading: Should You Switch To A Different Model?

Sometimes, pool owners wonder if they should upgrade instead of just replacing the old light with another Globrite. Here’s what to consider:

• If you want brighter, larger-area lighting, consider the Intellibrite or ColorLogic.
• If you want smart control with your phone, some new LED lights offer WiFi or app-based control.
• Older pools may need a niche adapter to fit different models.

Upgrading can cost more but may add value and enjoyment to your pool.

Real-world Example: Step-by-step Experience

Let’s look at a real example. Sarah, a pool owner in Texas, replaced her Pentair Globrite on her own.

Sarah noticed her pool light was flickering and had water droplets inside. She turned off the breaker, unscrewed the faceplate, and found the old cable was stuck. She used a garden hose to flush debris from the conduit, which freed the cable.

Using the old cable to pull the new one through, she installed the new light, added a fresh gasket, and double-checked all connections.

Her main advice: “Don’t rush. Take photos of every wire connection. Use lots of silicone on the cord stopper. My pool now glows better than ever!”

When To Call A Professional

While many handy pool owners can replace a Globrite light themselves, you should call a pro if:

• You are unsure about any electrical connection
• The cable is stuck or the conduit is damaged
• You see sparks, smoke, or water in the junction box
• Your pool uses high-voltage lights (120V) and you are not experienced

Licensed electricians have the tools and know-how to do the job safely and quickly.
